The structural formula of all the compounds that are named as a bromobutane is to be drawn. Concept introduction: The structural formula is a simplified model that represents the arrangement of atoms and bonds in a molecule. Compounds with same molecular formula but different structures are termed as structural isomers. In structural isomers, the arrangement of atoms is different. In the IUPAC name of an organic compound, the Greek prefix represents the number of substituents, the numbers before the Greek prefix or substituent represent the position of the substituents. The functional group may be represented as a suffix or as a prefix. Halogens are represented by ‘halo’ prefix. For example: if fluorine is substituted in the hydrocarbon chain, ‘fluoro’ prefix is used. The suffix for an alkane is ‘ane. The number of carbon atoms in the parent hydrocarbon chain is represented by the root name. For example: ‘prop’ represent three carbon atoms in the parent hydrocarbon chain.

A 0.552-g sample of an unknown acid was dissolved in water to a total volume of 20.0 mL. This sample was titrated with 0.1103 M KOH. The equivalence point occurred at 29.42 mL base added. The pH of the solution at 10.0 mL base added was 3.72. Determine the molar mass of the acid. Determine the Ka of the acid.
